Application filed May 18,

details of construction and combinations of parts, as will be hereinafter described and more particularly pointed out in the claims.

Referring to the drawings, in which like numerals of reference Vindicate like parts in the several figures; v

Figure 1 isa fragmentary elevation of my improved power mechanism, the parts in section being taken generally upon line 1 1 of Figure 2; f

Figure'2 is a fragmentary plan View thereof, the parts in section being taken generally upon line 2 2 of Figure l; and

Figure 3 is a detail view of the plane rings when nested the topmost ring, however, being shown in its partly assembled position.

In the embodiment of my invention as disclosed herein, 10 is the casing having offset portions 11 upon opposite sides thereof and closed at its ends by'cover plates 12, between which is a plurality of friction rolls 13.

Vithin the casing 10 arejthe sector shells 14, having a'plurality of teeth 15, in Vtheir outer walls, into which mesh the teeth of the sectors 16, which are fixed on shafts 17 journaled in the cover-plates 12.- The 'rolls 13 provide lateral support for these'sector shells without friction during rotation thereof which is also facilitated by the ball 'bearings 18. y

Fixed on the-shaft 17 is a pinion 19, the

teeth of which mesh intothose of a pinion 20,

fixed on a shaft 21 journaled in one of the cover plates 12. Y This latter shaft being manually rotated by a wrench 22, which may permanently associated therewith or ysepa-A rately, as desired.

That portion of the shaft 21 outside of the cover plate 12 may be square or hexagonal in cross section to receive the socket of the wrench, but a standard form of ratchet wrench may be substituted, if desired.

Within the casing is a cap plate 23, having a downwardly depending tiange 24 adjacent to its outer edge, and connected therewith is a rod 25 thatprojects through one of the cover plates 12, 'with a contact plate 26 fixedY thereto.

Nested Vbetween the cap plate 23 and the shelf 27, integral with the sector shells 14,

are two sets of plane rings,'each set being composed of several rings, all rotating about a common axis, and the rings in both sets being substantially alike, in yrelation to each other.

form, designated 28, having a flange 29 adjacent to the bore of,V theiring, and the other form designated 30, Shaving the flange 31 at the outer edge of the ring. these rings are so nested that the flange of one ring overlaps the body portion of the adjacent ring;

The top and bottom faces of each of these rings, as well as the innerl face of the cap plate 23, are each provided with a plurality of angular planes 32, which are provided with teeth 33 at their inner and outer edges. The planes of one ring are so arranged that they are oppositethe planes ofthe other ring and lproject inopposite directions, as illustratedk in'Figure 3.

Between each of these opposite planes is a toothed conical roll 34, the teeth of which mesh into the teeth 33 of the inclined planes.

' There are two forms of such rings, one` In either caser although staggered n The `arrangement of these rings "inthe sets Y is such that a ring in one set is in the same planeas a ring 30 of the opposite set and have an operative connection with each other through a link 35 pivotally Vconnected to lthese rings and projecting into a recess 36 in each ring.`

Mounted upon and projecting outwardly from eachof the rings'30 are a plurality of rolls 37, which projectv into recesses 38 in the inner wall of the sector shell 14.

Fixed to the shelf 27 of one of the Sector shells 14 is a ring 39, which formsa base for, V

Vthe plane rings nested thereabove, and to the l shelf21 of the opposite sector shell 14 a similar ring 40 rotatably mounted about a block 41 fixed Vto said shelf. Rotation of the shaft721 imparts movement to the Ashaft 17, and sector 16 to sector shells 14, and through the latter and the rolls 37 l to the plane rings 30. As the planerings 30 in one set of rings are connected with the vplane rings 28 of the opposite set through the links A'35, positive motion to each ring.

Y The rings 28 and'30 rotate in opposite directions and 'as the conical rolls '34 rotate about their axes through their toothed envis thus transmittedk gagement with the inclined planes, the plane i rings are forced apart, thus causing the cap plate 23 to travel toward the adjacent cover plate l2 and the contact plate 26 away therew from. Each ring is thus forced a limited distance away rom the adjacent ring but in the` aggregate the distance traveled by the cap plate 23 and contact plateQG is proportionately greater. Thus, with the application of comparatively limited manual power to the shaft 2l a great pressure maybe applied by Athe contact plate 26 to any object against which it may be placed. j

To prevent` the disengagement of the rolls 'when in their extended positions, each ring is associated with the adjacent ring through a plurality of balls 42, which travel in an inclined slot 43 in the adjacent wall oieach ring, by which means the rings are permitted i to move apart to the maximum distance and still retain the conical rolls therebetween.

There are minor changes and alterations that may be made within my invention, Aand I Y would therefore have it understood that I do Vnot limit myself to the exact construction herein shown and described, but claim all that falls fairly within the spirit `and scope of the appended claims. Y Having described my invention, what I claim as new and desire to secure by Letters Patent, is: j

l. In mechanism of, the character described; a plurality of rotary inclined planes, A said i'n'clined'planes beingarranged in a pluscribed; a plurality of rings having a com-v l mon axis and each ring vhaving one or more inclined planes thereon; rolls between the rings thatjcontactwith the inclined planes;

3. In mechanism of the character scribed; a plurality of ringshaving a. common axis and eachf ring having one or more inclinedplanes thereon; rolls; between the ringsthat contactr withV the inclined planes, each of the rings having a flange and the inclined planes thereon terminatingat one end adjacent to the flange; and means for rotating the rings whereby the rolls will move about their axes'v and the rings toward and away from each other.

rings that contact with the inclined planes, each of the rings having a flange and the inclined planes thereon terminating at one end adjacent to the flange; and means for rotating the rings whereby the rolls will move about their axis and the rings toward and.
